Method and system for managing network and storage data

1. A system comprising:

a computing system executing a storage application for sending an input/output (I/O) request for communicating with a storage device, the storage application transmits the I/O request to a storage driver that includes (a) an operating system interface to translate the I/O request to a storage protocol and to communicate with an operating system executed by the computing system, and (b) a storage protocol interface that executes operations related to the storage protocol for processing the I/O request such that the application can communicate with the storage device;

wherein the storage driver sends the I/O request to a network driver that encapsulates the I/O request into a combined network and storage packet; and

the encapsulated network and storage packet is transmitted via a network link using a network protocol.

2. The system of claim 1 , wherein the storage protocol is Fibre Channel.

3. The system of claim 2 , wherein the network protocol is Ethernet.

4. The system of claim 3 , wherein the encapsulated packet is a Fibre Channel over Ethernet (FCOE) packet.

5. The system of claim 1 , wherein the network link is an Ethernet link.

6. The system of claim 1 , wherein the computing system executes a network stack for processing Transmission Control Protocol/Internet Protocol (TCP/IP) packets.

7. The system of claim 1 , wherein the storage protocol interface is a Fibre Channel interface.

8. The system of claim 7 , wherein the Fibre Channel interface is partially executed by the storage protocol driver and partially executed within a network protocol stack.

9. The system of claim 7 , wherein the Fibre Channel interface is entirely executed within a network protocol stack.

10. A method for sending a storage packet encapsulated within a network packet, comprising:

receiving an input/output (I/O) request for communicating with a storage device from an application executed by a computing system; wherein the I/O request is received by a storage driver that includes an operating system interface to translate the I/O request to a storage protocol;

performing storage protocol-related operations for the I/O request, wherein a storage protocol interface formats the I/O request such that the application can communicate with the storage device;

the storage driver sending the I/O request to a network driver;

the network driver encapsulating the I/O request in a combined network and storage packet; and

transmitting the encapsulated network and storage packet via a network link using a network protocol.

11. The method of claim 10 , wherein the storage protocol is Fibre Channel.

12. The method of claim 11 , wherein the network protocol is Ethernet.

13. The method of claim 12 , wherein the encapsulated packet is a Fibre Channel over Ethernet (FCOE) packet.

14. The method of claim 11 , wherein the network link is an Ethernet link.

15. The method of claim 10 , wherein the computing system executes a network stack for processing Transmission Control Protocol/Internet Protocol (TCP/IP) packets.

16. The method of claim 10 , wherein the storage protocol interface is a Fibre Channel interface.

17. The method of claim 16 , wherein the Fibre Channel interface is partially executed by the storage protocol driver and partially executed within a network protocol stack.

18. The method of claim 16 , wherein the Fibre Channel interface is entirely executed within a network protocol stack.
